This study analyzed relations among maternal parenting behavior, infant development and parenting stress focusing on the moderating effect of parenting stress. Subjects were 30 infants and their mothers. After videotaping the mother-infant free play session, maternal parenting was analyzed by the Parent Child Interaction Play Assessment(Mash & Terdal, 1981); mothers' parenting stress was measured by questionnaire. Infant development was measured individually by the Korean Bayley Scale of Infant Development (K-BSID-II). Correlation analyses revealed that infant cognitive development correlated significantly with maternal parenting behavior (attention) but the relation between them was moderated by maternal parenting stress; only the low parenting stress group showed a positive relationship between maternal parenting behavior and infant development.

과학기술정보가 앞으로의 경제발전의 주도적인 역할을 수행할 지식기반사회의 핵심 요체임과 동시에 우리나라가 지식정보강국으로 도약할 기본적인 인프라임에도 불구하고 국가 지식정보시스템 개발에 따른 경제성장 및 제반 경제구조에 미치는 영향에 대한 분석은 현재 매우 미미한 실정이다. 이에 본 논문은 국가 지식정보시스템 개발의 연구활동이 경제 각 부문에 미치는 효과를 한국은행(2007)의 산업연관분석을 이용하여 생산유발효과, 부가가치유발효과, 수입유발효과, 취업자유발효과로 나누어 경제적 파급효과를 분석하고, 연구개발 투자에 대한 비용편익분석을 통해 국가 지식정보시스템 개발에 대한 경제사회적 타당성을 검증하고자 한다.

In this study, we investigated the effect of silkworm, and its by-products on exercise endurance, muscle mass, and fatigue recovery using ICR mice model. Powders of silkworm, pupae, dongchunghacho, and silk powder were suspended in water and feed to mice for 2 weeks. The forced swimming time was increased by 4.3, 4.1 and 2.8 seconds after silkworm, pupae, and dongchughacho administration compared to DW fed group. Increases in exercise ability were achieved by difference mechanism according to feeding materials. Pupae increased muscle mass by 129% compared with the control group which may effect on elongation of swimming time. Dongchunghacho improved the plasma concentrations of fatigue markers such as creatinine, blood urea nitrogen (BUN), and D-lactate. Silkworm administration showed dual effect, the muscle mass induction (114% vs. control) and anti-fatigue (plasma creatinine, BUN, and D-lactate were 63, 75, and 78% vs. con) effect which contributed most elongated swimming time. In conclusion, silkworm and its by-products including pupae and dongchunghacho with the predominant protein and bioactive components improved muscle mass and showed anti-fatigue effect which could promote exercise performance ability.

A total of 31 mothers of 5-month-old infants(18 boys and 13 girls) were observed and interviewed at home via a questionnaire format. Results revealed that perceived maternal parenting style had an effect on general infant general development. As mother exhibited more didactic and limit setting behaviors, the infants showed more receptive, expressive, and language development characteristics. Furthermore, the effects of maternal sensitivity on infant general development and language skills were also ascertained. The infants who showed more positive general development had mothers who interacted sensitively with them. Maternal sensitivity was the only factor that had a major effect on infant general development. The overall findings of this study indicate that perceived maternal parenting style and observed maternal sensitivity were found to have positive effects on general infant general development and language skills.

Crop development and nutrient availability are strongly influenced by soil salinity levels. This study was conducted to investigate the effect of rice straw and nitrogen (N) fertilizer for silage barley under various soil salinity levels at Saemangeum reclaimed tidal land. Three levels of rice straw (0, 2.5, 5.0 ton rice straw $ha^{-1}$) and N (0, 150, 225 kg N $ha^{-1}$) were applied at 0.04, 0.23, 0.35% soil salinity levels. Biomass yield of silage barley was influenced by the interactions between rice straw application and N fertilization. Although there was no single effect of rice straw application on biomass yield, it was significantly increased with N application and a rice straw application of 5.0 ton $ha^{-1}$. Sodium content in silage barley was significantly lower at 0.04% salinity level, and but it was statistically increased with increasing soil salinity levels. Forage qualities such as total digestible nutrients and relative feed value of silage barley were significantly higher with N application at 0.04% salinity level, but there was no effect of rice straw application. Soil organic matter content was increased with N and rice straw application regardless of soil salinity level. The results of this study showed that the effect of rice straw and N fertilization on silage barley was influenced by soil salinity levels, which indicates that the management practice of silage barley at Saemangeum reclaimed tidal land should consider soil salinity levels.

Purpose: The purpose of this study was to investigate if purchasing companies' efforts of supplier development activities to supplier companies have positive impacts on the purchasing companies' performance as the first step. In the second step, we tried to confirm if the concept of Supply Chain Corporate Social Responsibility activities and Coexistence activities take the roles of moderate variable on relationship between supplier development and three performances respectively. Methods: The collected data through survey were analysed using multiple regression for the first step of the study and moderate regression for the second one of it. Results: The results of this study are as follows; supplier development efforts effect on all three performances positively. Moreover, Supply Chain CSR has significant moderate effect on relationship between supplier management and corporate performances, while Coexistence does between supplier management and logistics performances. In the case of relationship between supplier management and production performances, both Supply Chain CSR and Coexistence show significant moderate effect. Conclusion: Manufacturing companies in Korea need to make effort of supplier development in selective way when they want to practice Supply Chain CSR and Coexistence concurrently considering strategies and objectives.

Over the past decades, financial markets have been integrated across countries while income inequality has increased in most countries. This paper studies the effect of financial market integration on income inequality and investigates whether this effect varies with the degree of financial market development. We find empirical evidence that financial market integration and financial market development interact to change income inequality. Specifically, the effect of financial market integration on income inequality is nonlinear, and the degree of financial market development plays an important role. Opening financial markets worsens income inequality in the countries holding the underdeveloped state of financial markets, however, the effect of capital account openness on income inequality is statistically insignificant in the countries with developed financial markets.

Wound healing and antibacterial effects of solcoseryl-micronomicin combination gel on an open wound were studied in mice. A simple model was designed for assessing the effects. Using the model, we compared the efficacy of a combined topical gel of solcoseryl and micronomicin with those gels of solcoseryl or micronomicin alone. From the results of our experiment, the wound healing effect of open wounds by treatment with the combination gel was significantly enhanced when compared with those by treatment with solcoseryl gel or micronomicin gel alone. And the antibacterial effect of the combination gel was higher than those of solcoseryl gel or micronomicin gel alone.

This study was planned to investigate the effects of mathematical games with motion on young children's development. The study was performed to compose mathematical games with motion and just mathematical games for young children. The games were set up to be executed 16 times for 8 weeks. The results of this study were as follows: Mathematical games with motion had a significant effect on young children's mathematical problem-solving ability. Mathematical games with motion had a significant effect in every category on young children's ability for motion competence and mathematical games with motion had a significant effect on young children's socio-emotional development. There were significant differences between the control group and the experimental group except for the independence from teachers and peer interaction. Mathematical games with motion had a significant effect on young children's language ability.
